Özet
Bu araştırmada materyal olarak Kolibri F 1 ve Korist F 1 alabaş (Brassica oleracea var. gongylodes L.) çeşitleri kullanılmıştır. Bitkiler, ısıtmasız plastik serada sera toprağında yetiştirilmiştir. Tohumlar torf doldurulmuş multipotlara ekilmiş ve ilk gerçek yapraklar görülünceye kadar standart bakım işlemleri yürütülmüştür. Fideler ilk 4-5 yapraklı olduğu dönemden itibaren seraya dikilmiş ve iki farklı vejetasyon döneminde farklı konsantrasyonlarda hazırlanan tuzlu su ile sulama yapılmıştır. Bu amaçla alabaşın iki farklı vejetasyon döneminin başından (genç fide döneminden gövde başlangıcına kadar, gövde başlangıcından hasada kadar) itibaren sulama suyuna dört farklı dozda NaCl tuzu (Kontrol, 5 dS/m, 10 dS/m ve 20 dS/m) ilave edilmiştir. Deneme tesadüf parselleri deneme desenine göre 3 tekerrürlü olarak kurulmuştur. Tüm denemede toplam 48 parsel, her parselde 10 bitki ve tüm denemede toplam 480 bitki kullanılmıştır. Sonuç olarak, sulama suyundaki NaCl konsantrasyonundaki artışa paralel, yaprak sıcaklıklarında ve hasar indeksinde artış gözlenirken, diğer morfolojik ve fizyolojik özelliklerde düşüş gözlenmiştir. Bitkilerin genç fide döneminden gövde başlangıcına kadar tuz stresinden daha fazla etkilendiği, ayrıca Korist F 1 'in tuz stresinden Kolibri F 1 'e göre daha az zarar gördüğü belirlenmiştir.
In this study, Kolibri F 1 and Korist F 1 (Brassica oleracea var. gongylodes L.) kohlrabi cultivars were used as material. Plants were grown in the soil of an unheated plastic greenhouse. Seeds were sown in peat-filled multipots and standart cultural practices were done until the first true leaves appeared. The seedlings were transplanted into the greenhouse starting from the period when they had the first 4-5 leaves and were irrigated with salt water prepared at different concentrations in two different vegetation periods. For this purpose, four different doses of NaCl salt (Control, 5 dS/m, 10 dS/m and 20 dS/m) were added to the irrigation water from the beginning of two different vegetation periods (from the young seedling period to the beginning of the stem, from the beginning of the stem to the harvest period). The experiment design was randomized plot with 3 replications. A total of 48 plots, 10 plants in each plot, thus a total of 480 plants in the whole experiment were used. As result, in parallel with the increase in NaCl concentration in irrigation water, an increase was observed in leaf temperatures and damage index, while other morphological and physiological characteristics were down. It was determined that plants were more affected by salt stress from the young seedling period to the stem beginning, also Korist F 1 was less damaged by salt stress than Kolibri F 1 .
